Modifying existing formats
The following procedure demonstrates how to modify the parameters of an existing format
using the command interface. This example changes an existing digital format from RGB
4:4:4 to YCbCr 4:2:2, and saves the format into the default format directory.
To edit an existing format:
1. Establish a terminal session with the generator.
2. Set the generator to digital friendly mode:
SROP 2 (or SROP 2 4) // sets generator to digital friendly mode
SROP 8 // sets generator to status display mode
3. Load and begin editing the format:
FMTL existing_format // loads existing format into format editor
FMTB // begins a format editing session
4. Enter the format parameter commands in sequence where the values differ from the
default values. For example to modify the component video type enter the following
command:
DVST 14 // changes the component color to YCbCr
DVSM 2 // changes component color make up to 4:2:2
ALLU // loads hardware and outputs new signal
5. End the editing session and save the format using the following commands:
FMTE // ends the format editing session
